Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Battery-free high-definition video streaming: There's a system for that

University of Washington researchers have developed the first analog video backscatter system for high-definition (HD) video streaming from low-power or battery-free devices. The new system burns as low as 250uW for HD video streaming, which is 1,000 times to 10,000 times less power than existing approaches, by eliminating the power-hungry components of a typical camera -- enabling battery-free HD streaming from devices such as lightweight wearables and wireless security cameras.
